Hyogo Kobe City
A serene hot spring inn that restricts entry to guests under junior high school age. Relax on an adults-only holiday with public baths and saunas filled with Arima’s famed Kinsen.
"Nakanobo Zuiun" is a long-established and prestigious inn in the heart of Arima Onsen, with a history stretching back to the Meiji era. As an adults-only retreat that restricts entry to guests under junior high school age, it preserves a quiet, private, and refined atmosphere. The inn’s greatest appeal is the chance to fully enjoy Arima’s famed healing waters, Kinsen and Ginsen. The two distinctive public baths, Zuisen and Soosen, operate on a gender-swapping basis, and each offers an open-air bath and indoor bath filled with the rich reddish-brown Kinsen. In addition, each bath area is equipped with a medium-low-temperature dry sauna that lets you work up a deep, comfortable sweat at your own pace, along with a pleasantly cool one-person cold plunge bath. Soosen also features a moist, soothing mist sauna. Furthermore, the private open-air baths, available free of charge and secured with an interior lock, let you enjoy clear Ginsen (radon spring) in complete privacy, offering the ultimate bath-hopping experience.
The signature Kinsen of Arima Onsen, used in the indoor and open-air baths of the Zuisen and Soosen public bath areas. This strong salt spring is extremely rich in iron and salt, and turns reddish-brown when exposed to air. It offers excellent heat retention and moisturizing effects, warming the body through to the core and promoting circulation.
Clear, transparent, and smooth Ginsen (radon spring) poured into the private open-air baths available for exclusive use. As a radioactive spring, it is expected to help activate metabolism, boost immunity, and relieve fatigue. Enjoy an exceptional private hot spring experience while feeling the calm atmosphere.
A woody, clean dry sauna installed in both the Zuisen and Soosen public baths. The temperature is not overly high, but the moderate humidity encourages a slow, comfortable sweat deep within the body. In this tranquil space, you can enjoy a calm and unhurried sauna session.
A moist and soothing mist sauna located in the open bath area of Soosen. Gentle steam envelops the body, warming you softly while keeping your skin hydrated. It is also recommended for those who do not like intensely hot saunas, allowing for relaxation with less strain on the body.
A luxurious one-person cold plunge bath located right next to the sauna room. The water temperature is not excessively cold, allowing your body to cool down gently after the sauna. In the clean and refreshing space, you can relax at your own pace and enjoy the feeling of tottonou without worrying about those around you.
Day-use bathing: not available (for overnight guests only)
